Abstract (en)
The object of the present invention is to provide a new organic phosphorus ligand that can efficiently promote cross-coupling reaction to obtain the target substance at high yield, as well as a method of manufacturing such ligand whose steric characteristics and electronic characteristics can be fine-tuned and which can be used to cause cross-coupling reaction at high yield. As a means for achieving the aforementioned object, a phosphine compound expressed by General Formula (1) below is provided. (In the formula, R 1 and R 2 are each independently a secondary alkyl group, tertiary alkyl group, or cycloalkyl group, while R 3 and R 4 are each independently a hydrogen, aliphatic group, heteroaliphatic group, aromatic group, alicyclic group, or heterocyclic group. Note that R 3 and R 4 have no phosphorus atom and that R 3 and R 4 are not both hydrogen at the same time).
